Title: Failure diagnostic device for evaporative emission control system
Inventor: MATSUMOTO TAKUYA
IPC: F02M25/08
Filed: 1994-09-30
Abstract: PURPOSE: To reliably diagnose failure or malfunction of a purge control valve provided on a fuel evaporation gas discharge restraining device. CONSTITUTION: When an engine 1 is in the specified driving state after warming, an ECU 2 stores the mean value I of the integral terms of air-fuel ratio feedback control and engine speed NE, and then releases and drives a purge control valve 46, thereby, purge air is introduced into an intake pipe 9. After purge air is introduced, the mean value I of the integral term or the engine speed NE are again stored. When the change of the value across introducing of purge air is hardly detected, the failure of the purge control, valve 46 is diagnosed.

Title: Method and device for controlling transmission of traffic of two class
Inventor: YORAN OFUETSUKU
IPC: H04L12/433
Filed: 1992-09-04
Abstract: PURPOSE: To allow the method to transmit two-class traffic onto a ring network. CONSTITUTION: So long as an existing protocol permits, two-class traffic is sent onto a ring in a ring network where nodes 10 are connected through links 13, 14. After a 1st control signal is circulated through the network at least only once, when the 1st control signal reaches a station having a back log of traffic of the 2nd class, the 1st control signal is changed into a 2nd control signal. The 2nd control signal is circulated only once through the ring network to indicate it to each station that the 2nd control signal cannot send traffic of the 1st class. The traffic of the 1st class is normally ascynchronous data and the traffic of the 2nd class is to synchronous data.

Title: Capacitive sensor
Inventor: OKUMURA MASUSAKU
IPC: G01B7/00
Filed: 1992-07-22
Abstract: PURPOSE:To realize high accuracy and low price by applying an isolated electrode to a plastic cylinder. CONSTITUTION:An outer electrode of a capacitive sensor comprises a cylindrical plastic 1, an electrode 2, an electrode isolating part 3, a reinforcing rib/electrode isolating part 4, and a protective film 5. The circuit of the capacitive sensor can be represented equivalent by a capacitance 6 at the cylindrical plastic part defined by the height and quantity of liquid or solid to be measured filled in the cylindrical plastic 1, a capacitance 7 of the liquid or solid, and a resistance 8 of the liquid or solid. Consequently, the height and volume of the liquid or solid can be measured based on the variation of capacitance for both capacitive and conductive liquid or solid. The capacitive sensor can measure the type, volume, and capacitance corresponding to the height of liquid or solid directly based on the permittivities(conductivities) of sensor material and a material to be measured, resulting in a highly accurate, low price capacitive sensor having simple structure.

Title: Error generator
Inventor: TOUKADO TETSUO
IPC: G06F7/58
Filed: 1990-09-07
Abstract: PURPOSE:To attain the generation of a random error pattern of data by arranging several types of M series generators and then selecting these generators according to the M series. CONSTITUTION:A comparator 4 compares the output of an error rate setter 5 with the output of an M series generator 3, and the output is given to a selector 7 only when the difference between both outputs exceeds the set level of the setter 5. When the selector 7 selects one of (m) pieces of generators 3 through an M series generator 8 used for the selector 7, the data on a data input terminal 1 corresponding to the set level of the setter 5 is inverted by a data inverter 6. This inverted data is outputted. Thus an optical error pattern is obtained.
Patent JP-H0286998-A (JP)
Title: Blower
Inventor: SHINODA YUKIO
IPC: F04D29/32
Filed: 1988-09-22
Abstract: PURPOSE:To secure such a blower that is low in a temperature rise, high in strength of a blade and excellent in reliability and service life by installing each recess part in open ends of a boss part of the blade at the blade side, while setting up an end of the blade in a projection being formed between these recess parts. CONSTITUTION:When air is inhaled from a base block 1 on one side and sent to it on the other, air lying between a stator 4 and the sticking surface 8c of a turning shaft 7 of a boss part 8 is stirred by a stirring rib 14 and thereby heat exchange being produced by the stator 4 is made so better. The air raised in temperature by the heat exchange is entered in a vent passage 13 from a clearance of a base 12, and then it is discharged to the outside of a blade 8 from a recess 15 at an end of the boss part 8a. On the other hand, from the outside of the blade 8, it is inhaled in the boss part 8a from a clearance between the stator 4 and a rotor magnet 10 as cooling the stator 4. At this time, since the recess 15 is installed and an open area is large enough, a cooling effect becomes enlarged. In addition, since an end of a blade 8b is set up so as to become a projection 16, strength is also enhanced.
